甘肃省居民对市售熟肉制品中亚硝酸盐的暴露评估

目的了解甘肃省市售熟肉制品中亚硝酸盐的含量,并对造成的人群健康风险进行评估。方法采用非连续3 d 24 h回顾方法入户调查1 466名居民的肉类食物消费状况,并结合363份市售熟肉制品中亚硝酸盐含量检测数据,采用简单分布的方法获得人群熟肉制品亚硝酸盐每日暴露量,并与亚硝酸盐的每日允许摄入量进行比较,评估甘肃省居民熟肉制品亚硝酸盐暴露风险。结果甘肃省市售熟肉制品中亚硝酸盐检出率为85.40%(310/363),超标率为3.31%(12/363),平均含量为7.76 mg/kg。甘肃省居民熟肉制品中亚硝酸盐每日平均暴露量为0.002 3 mg/kg BW,高端消费人群暴露量(P97.5)为0.008 3 mg/kg BW,为每日允许摄入量的11.86%。结论甘肃省居民通过熟肉制品摄入的亚硝酸盐所致的健康风险较低,但仍需对市售熟肉制品中亚硝酸盐的规范使用加强监督。

Nitrite exposure assessment of commercial cooked meat products for Gansu residents

Objective To understand the nitrite residual content of commercial cooked meat products in Gansu,and assess the health risks. Methods Through the meat consumption survey about of 1 466 residents by non-continuous 3 day 24 hour review method, combined with the detection data of nitrite content in 363 commercial cooked meat products, daily nitrite exposure was obtained by simple distribution method, compared with nitrite acceptable daily intake, and the nitrite exposure risk in Gansu residents was assessed. Results Nitrite detection rate of commercial cooked meat products was 85.40% (310/363) in Gansu Province, the violation rate was 3.31% (12/363), and the average content was 7.76 mg/kg. Daily nitrite exposure from meat was 0.002 3 mg/kg BW on average, and the high exposure was 0.008 3 mg/kg BW, account for 11.86% of the acceptable daily intake. Conclusion There was no safety concerns from meat nitrite for residents in Gansu Province, but the reasonable use of nitrite in cooked meat products should be improve.
